Simplify 4x + 3x² + x² - 3x
Answer:
[tex]x + {4x}^{2} [/tex]
Step-by-step explanation:
simplify by combining like terms
4x - 3x = x
[tex]3x ^{2} + {x}^{2} = {4x}^{2} [/tex]
we're left with
[tex]x + {4x}^{2} [/tex]
Answer:
4x²+x
Step-by-step explanation:
4x-3x+3x²+x²
4x minus 3x is x and 3x² +x² is 4x²
therefore,
4x²+x

The volume of the Moon is about 2.8 x 10^10 cubic kilometers. The volume of Earth is about 1.9 x 10^12 cubic kilometers. The number of Moons that can fit inside Earth can be found by dividing Earth's volume by the Moon's volume. About how many Moons can fit inside Earth?
Answer:
50 moons can fit inside Earth.
Step-by-step explanation:
The Volume of Earth is
1.09 × 10 ^12
cubic kilometres
The Volume of The Moon is
2.18 x 10^ 10
cubic kilometers
Hence the number of Moons that can fit in Earth is
Step-by-step explanation:
what is the arc length of s in the figure below
Answer:
2.18ft
Step-by-step explanation:
what is the arc length of s in the figure below
Length of the arc = theta/360 * 2πr
r is the radius = 1ft
theta = 125 degrees
Substitute into the formula
Length of the arc = 125/360 * 2(3.14)* 1
Length of the arc = 785/360
Length of the arc = 2.18ft
Hence the length of the arc is 2.18ft
X^2+3x-18 what are the zeros of r(x)?
Answer:
Step-by-step explanation:
18 has factors of 9 and 2 or 6 and 3
Those factors must differ by 3, so 6 and 3 in some order is your answer.
(x + 6) (x - 3) = r(x)
You have to make x a value that turns the factor into 0.
x + 6 = 0
x = - 6
x - 3 = 0
x = 3
So the zeros are (3,0) and (- 6,0)
Suppose you roll a special 33 sided die. What is the probability that the number rolled is a one or a two?
Answer:
2/33
Step-by-step explanation:
Chance of rolling a 1 is 1/33, chance of rolling a 2 is also 1/33. so add the probabilities 1/33 + 1/33 =2/33

Can somebody please help me with this ?
Answer:
8x, 2x^2, 6xy, 5y.
Step-by-step explanation:
Hello, 5x+3x would be 8x since 5+3 is 8. 7x^2-5x^2 would be 2x^2 since 7-5 is 2 (exponents stay the same). 2xy+4xy is 6xy since 2+4 is 6. Lastly, 8y-3y is 5y since 8-3 is 5.

If a fraction is equal to 2/9
and the sum of the numerator and denominator is 99, what is the fraction?
Answer:
18/81
Step-by-step explanation:
the current fraction adds up to 11 so to get 99 you would need to multiply both the numerator and the denominator by 9 to get a sum of 99
so 2 x 9 = 18 and 9 x 9 =81
so answer is 18/81

Unit 11 Homework 1: Area of Plane Figures
Answer: 4. 432 cm^2/2 = 216 cm^2
6. 309.76 mm^2
8. pi * 22^2 = 484pi (or, approximately 1,519.76) in^2
484/2 = 242pi or 759.88 in^2.
10. 297.84 in^2/2 = 148.92 in^2
Step-by-step explanation:
To find the area of a triangle, you take the base and multiply by the height, and then divide by 2. Hence giving me the answers I obtained in #4 and #10.
A square is equal on all sides, so you would just square the measurement of the one side.
To find the area of a circle, you would do pi times the radius^2. Since this is a semicircle, you actually should divide the number you got by 2. (Which is why I did so up above).

14ab5 - 2ab5 + 4b2 +b
Answer:
80ab + 9b
Step-by-step explanation:
Step 1: 14 x 5 + 2ab x 5 + 4b x 2 + b
Then......
Multiple the numbers: 14 x 5 = 70
Step 2: = 70ab + 2 x 5ab + 4 x 2b + b
Then......
Multiple the numbers: 2 x 5 = 10
Step 3: = 70ab + 10ab + 4 x 2b + b
Then......
Multiple the numbers: 4 x 2 = 8
Step 4: = 70 ab + 10ab + 8b + b
Then......
Add similar elements: 70ab + 10ab = 80ab
Step 5: = 80ab + 8b + b
Then......
Add similar elements: 8b + b = 96
80ab + 9b
